SPECIFICATION forming part of Letters Patent No. 407,850, dated July 30, 1889.

Application filed April 13, 1889. Serial No. 307,096. (No model.)

To all whom, it may concern.- 1. Fig. 8 is a transverse vertical section in Be it known that I, NATHANIEL A. BOYN- the line i) c of Fig. 1. .TON, a citizen of the United States, residing In the construction of the heaterA,the sevin the city of New York, in the county of New eral intermediate water-containing sections 55 York, in the State of New York, have invented A A A A &c., in any desired number, are a new and useful Hotater Heating Appaplaced face to face, the outer vertical port-ions ratus, of which the following, in connection a a and the transverse horizontal portions with the accompanying drawings, is a dea a being in close contact, so as to form a scription. tight joint.

on the line 2 3 in Fig. 1. Fig. 7 is a trans- It will be seen that under the construction verse vertical section in the line a a of Fig. shown and described two distinct heat-currents ascend from the lower to the upper extremity of the water-heater, the water received through the opening 00 passing upwardly by zigzag currents from the right toward the left, and the water received through the openings a passing upwardly by similar zigzag currents from the left toward the right, the two currents being kept apart on the right by the vertical partitions a and 04 and on the left by the vertical partitions a and a By these the ascending currents are prevented from intermingling until they meet at the junction of the passages c0 and (4 below the exit-openings t at the top of the heater. 7

It will be noted in Figs. 2 and 3 that the lowermost half-flue or cutaway portion of the transverse water-passage is of greater transverse extent than the half-fiues above it. The object of this construction is to equalize thecombustion of fuel, as it will be apparent that if the exit were too far to the right of the fuel-chamber the combustion at the extreme left of such chamber would be very materially diminished, if, indeed, it were not wholly prevented.

For an analogous rea on the smoke-exit opening a in the rear closing-plate A is placed nearer to the right than to the left of the heater, thereby causing the smoke to be carried farther toward the right in seeking its exit, and thus as a consequence more equally heating the upper transverse waterpassages, more especially those which are nearest the rear of the heater.

In Fig. 3 the feathered arrows denote the course of the products of combustion, the unfeathered arrows indicate the course of the water-currents, which are received at the right through the openings C634, and the unfeathered single-barbed arrows represent the direction of the water-currents which are rea and a, in which position they are so re-.

mote from the point of greatest heat as not to be unduly expanded thereby, while at the same time they present no appreciable obstruction to the movement of the water-currents, or of the heat-currents, alongthe passages.

As already stated, the exterior portions of the water-sections are so closely fitted together as to be proof against escape of smoke or gases. The intermediate portions of the sections alsothat is, the horizontal waterpassageswill be in close proximity, so as practically to prevent passage of products of combustion, except through the vertical openings produced by the juxtaposition of two half-fines, as already indicated; but they will not be so closely fitted that their greater expansion will cause the joints of the exterior portion of such water-sections to open.

- The coincident web-like formations or ribs 60 and c0 extending along both the vertical and the transverse portions of the sections serve both to strengthen the same and to more effectually utilize th'e'heat evolved from the burning fuel by presenting at either side of the combustion-chamber a series of obstructions, which have the effect of retarding the currents of heat and preventing their too rapid escape.

As will be seen in Fig. 7, the front closingsection A has a vertical water-passage, as p, at each side, a horizontal water-passage, as 19, below the fuel-supply opening, a horizontal passage 13 above the clearing-door opening, and a horizontal passage 19 between these two openings. As seen in Fig. 8, the rear closing-section A which, like all the other sections, is cast in a single piece, is made plain in its upper and lower portions, but intermediately is formed with coincident front and rear corrugations a 0, which, although slightly asunder at their nearest points, constitute in effect vertical tubes or water-passages a which connect the horizontal water chamber or passage 00 at the bottom with the corresponding transverse water-passage a at the upper extremity of the section, through which portion, from front to rear, extend the walls of the short longitudinal smoke-flue or exit-opening a These end or closing sections A A are so formed at their outer, upper, and lower extremities as to communicate with the adjacent intermediate water-sections. The tubular formation of the rear closing-section at the extremity of the fuel-chamber is designed to insure thorough utilization of the heatproducts at this point.

Having described my invention, I claim- -1. In a hot-water heating apparatus, a transversely-placed water-section which extends from side to side of the heater, and which has two distinct sinuouswater-passages, each of which extends from the lower to the upper extremity of such heating apparatus.

2. In a hot-water heating apparatus, a water-section which extends from side to side of such apparatus, which is provided with vertical water-passages and with horizontal water-passages, and which is provided, also, with right and left vertical partitions which separate such vertical and horizontal water-passages into two distinct series of passages, each series of which embraces both vertical and horizontal water-passages, substantially as described.

3. In a hot-water heating apparatus, the combination, with the intermediate watersections, each having exterior vertical waterpassages and each having horizontal water- .passages, as a a, which extend inwardly from such exterior vertical water-passages, of the rear closing-section A, provided with eccentrically-placed smoke-exit opening a substantially as and for the purposes set forth.

at. A hot-water heating apparatus in which the water-heater is composed, essentially, of a front closing-section, a rear closing-section, and a series of intermediate water-sections, each of which has right and left vertical water passages or legs, which constitute the side walls of the fuel-chamber, vertical passages above such side-wall passages, horizontal water-passages which extend inwardly from such higher vertical passages, and lateral, reduced, or cut-away portions beyond the inner extremity of such horizontal passages, which together constitute vertical smoke-passages between lower and upper smoke-spaces, the

front and rear closing-plates and the sections between them being secured together, substantially as specified.

5. In a hot-water heating apparatus, the series of water-circulating sections A and A each provided with the web-like strengthening and retarding ribs and 0, extending along both the vertical and the transverse portions of such sections, as described and shown.

6. In a hot-water heating apparatus, the combination, with the intermediate water-sections, of the rear closing water-section, communicating on either side at top and bottom with such intermediate water-sections, and provided with a smoke-flue which extends longitudinally through such closing-section.

7. In a hot-Water heating apparatus, the combination, with the intermediate water-sections, of the rear closing water-section having a transverse water-passage at top and at bottom, and a series of intermediate Vertical tubular water-passages, which connect such top and bottom transverse water-passages.

8. In a hot-water heating apparatus, the combination, with the central or intermediate water-sections, of the front closing water-section, provided with a clearing-opening and with a fuel-supply opening, and having right and left vertical water-passages, top, bottom, and intermediate transverse or horizontal water-passages,and rear'openings which are coincident with the longitudinal water-passages of the intermediate water-sections.
